The circuit given here is a current limited lead acid battery charger built around the famous variable voltage regulator IC LM 317.
To setup the charging voltage, power ON  the charger and hook up a voltmeter across the output terminals and adjust R4 to make the voltmeter read 28V. I Have 36 volt 10 AH lithium battery, can I modif 24V lead acid battery charger circuit, to charger my 36 volt lithium battery? Hello engr,in this your design.can i use it to charge two 12V,26AH lead acid battery connected in series?.if no,what is the implication? Two 12 volts batteries of similar type and conditions can be charged up to a maximum of 7 AH only. Hi joe Two 12 volts batteries of similar type and conditions can be charged up to a maximum of 7 AH only. Hello engr,in this your design.can i use it to charge two 12V,26AH lead acid battery connected in series.if no,what will be the implication? Hello would you be kind enough to publish a 48v 5 to 10 amp lead acid battery charger circuit ? This charger can be used for single 24 volt 7 AH battery or 2nos 12 volts 7AH batteries in series.
Hi Tran you can charge 24volt 1.3AH battery (hope dry means dry fit lead acid gel cell) also. Thank you very much for the charger circuit, i would like to use this circuit for charging two lead acid (12v 150A X 2)battery, for inverter.
Sorry, I can’t quite follow how the resistor R2 provides 700mA, can you explain how the calculation is done please?
I am looking to make an in-car charging system for an electric mobility scooter – it uses a 24v 10Ah battery. 1) can I substitute a 12v step-up DC-DC converter for the transformer and bridge rectifier section of your circuit to give me the DC input to the regulator, and what output voltage would the converter be required to supply?
2) what if any of the components of the regulated charger section would need to be changed to provide the correct output current and voltage?
I’m a big fan of your circuits,and I would like to ask about the possibility of modifying this circuit so we can control charging current (like a pot.
Hi Gangadhar you can but ensure the output voltage is adjusted to 14.2 volts without load with pot R4.

Setting up a webcam sight illuminator over your laptop's webcam will certainly “enlighten” your online conversations. The circuit uses a variable voltage regulator IC LM 317 to set the output voltage steady around 16 volts. This drains the output current from the regulator IC through T1 and charging process stops.
The circuit should stop work when the battery is charged , and start work when the battery is discharge.the battery charging should be safely.
I want a controller that protects overcharging, discharging of the battery and shows when the battery is full.

We require chargers for 12V 9 Ah batteries on a regular basis, our initial order is 500 pcs , please contact me on zenithagro at hotmail dot com or zaindus at hotmail dot com. Hi RAM you require a regulated 14volt DC supply with the current limiting fixed at 5Amps max. How do we modify this circuit to charge one or multiple units of SMF 5-volt motorcycle batteries. This is the circuit diagram of a very powerful and efficient Ni-MH battery charger using IC LT4060 from Linear Technologies. Hi Rohit you require an external ballast, you can use a 20 watt flurescent light ballast for this lamp as it has got its own built in starter. I added a image of the CFL light, as you can see it does not have a driver or a ballast attached, hence iam requesting your help. Hi Rohit you donot require any ballast for these CFLs as they are with built in electronic switching supply to take care of 170 to 270 volts AC.
Can you help me with a circuit diagram for a 26 watt CFL, single pins (only two pins on the 26 watt CFL). A beautiful diy gsm jammer or mobile cell phone jammer schematic diagram for use only in GSM1900 with frequency from 1930 MHz to 1990 MHz. The GSM jammer circuit could block mobile phone signals which works on GSM1900 band, also called DCS.

As per your requirement of 26 AH a power pack capable of maximum current limit of 7 amps (9 amps preferred) is required. Pls I need your urgent assistance in responding to these questions to enable me modify this circuit to do something else.
I tried to insert a second BC547 as suggested (base of 2nd BC547 to base of 1st and emitter to the other emitter and collector to a led and a 2.7K resistor to C1 positive) to indicate full charge with no luck whatsoever!
Pls can u send me the circuit diagram containing the charging indicator(green and red).pls send it to my email. When the battery voltage reduces below 12 volts, ZD1 turns off and battery charging starts again. The GSM1900 mobile phone network is used by USA, Canada and most of the countries in South America.

When the solar panel generates current, D1 forward biases and Regulator IC gets input current. By altering the connections of SEL0 and SEL1 pins, upto 4 batteries in series can be charged using this circuit. Its output voltage depends on the setting of VR and the output current is controlled by R1. When the battery attains full voltage around 13 volts, Zener diode ZD1 conducts and T1 forward biases.
Diode D1 prevents the reverse flow of current from the battery when charger is switched OFF or when mains power is not available. When the output voltage is above (as set by VR) 16 volts, zener diode ZD2 conducts and gives stable 15 volts for charging. The circuit also features temperature based charge qualification.An NTC thermistor connected at the NTC pin (pin11) of the IC serves as the temperature sensor.
